Considering that five fights could take at least two-and-a-half years to carry out, it always seemed slightly odd that Mayweather could place a firm timetable on when he would retire.

In that amount of time, there are so many unforeseen circumstances that could alter a boxer's career. He could get injured, suffer a loss, suddenly lose his love for the sport or any number of other things.

On the flip side—and this is what Mayweather is referring to—if he continues to look like he did against Guerrero in his next five fights and still feels like the obvious choice for best in the world once he moves to 49-0, five may not be enough.

The future is unpredictable, and five more fights is by no means a number etched in stone.

Mayweather, of course, has a huge matchup on the horizon with Saul "Canelo" Alvarez in September.

Canelo is only 22 years of age, but at 42-0-1 and fresh off a dismantling of Austin Trout, he is one of the brightest young fighters in the sport. At the very least, he has the size and offensive arsenal to put Mayweather's legacy to the test.

Whether or not "Money" wants to extend his career after that fight remains to be seen, but if he continues picking apart all of his opponents, the five-division world champ could stick around longer than we previously anticipated.
